Calorimeter CWD

Calorimetry, Wobbe-Index and specific Density

The CWD2005xxx-device series Calorimetry, Wobbe-Index und Specific Density) comprises versions of combustion calorimeters for direct and continuous determination of gas quality from the following measurands and operands:

Wobbe-lndex

Specific density

Heating and combustion values

Combustion Air Requirement (CARI) and air requirement, with integrated gas analysis

Energy quantity, with expanded system EMS2005BCR.

The Wobbe index and specific density are measured, and the heating value and combustion value are calculated from these measurements.

When components for gas analysis are added to the CWD2005, the air requirement, or CARI, can also be determined from the analyzed gas composition.

The operating principle of the CWD enables all combustible gas components to be detected, which allows it to be used even for gases with rapidly changing gas composition.
